Answer:
True
Explanation:
With the increase in altitude, the atmospheric pressure and amount of oxygen decreases.
When a person moves to high altitude, they adapt to the lack of oxygen by increasing their red blood count and the process is called acclimatization. The lack of oxygen is monitored by the peripheral chemoreceptors, that increases ventilation. The body starts producing red blood cells (RBC) in order to resist the lower oxygen saturation in blood in high altitudes.
That is why, people living in high altitudes have higher red blood cells count in comparison to people living in cities or plain areas.
Hence, the given statement is true.
Answer:
Unsaturated zone: The area between the soil-water belt and the water table where pore spaces are not saturated with water. Saturated zone: The zone of rock below and including the water table where pore spaces are completely filled with water.

The correct answer is option A
The burning of fossil fuel releases carbon dioxide in the environment. Carbon dioxide is the main green house gas. The green house gases work by trapping the heat that comes inside the earth from the sun.
The carbon dioxide is the green house gas that traps maximum heat coming from the sun. If the carbon dioxide would not have been there then the temperature of the earth would have been very low and the atmosphere would have been colder.
But the global temperature is rising due to lost of carbon dioxide present in the environment as the burning of fossil fuels is increasing day by day.
